A solution has a pH of 2.5. what is the H+

romanna [79]

<u>Answer: </u>The concentration of $H^+$ in the solution is $3.16\times 10^{-3}M$

<u>Explanation:</u>

pH is defined as the negative logarithm of hydrogen ion concentration present in the solution.

$pH=-\log [H^+]$ .....(1)

We are given:

pH of solution = 2.5

Putting values in equation 1, we get:

$2.5=-\log [H^+]$

$[H^+]=10^{-2.5}$

$[H^+]=3.16\times 10^{-3}M$

Hence, the concentration of $H^+$ in the solution is $3.16\times 10^{-3}M$

Horticulturists know that, for many plants, dark green leaves are associated with low light levels and pale green with high leve

nikitadnepr [17]

In the reduction process of photosynthesis, electrons are transported from water to carbon dioxide.

According to photon theory here the photons behave as light energy particle.
By capturing sun energy (photons), chlorophyll aids in this process.An electron in the chlorophyll molecule gets excited from a lower to a higher energy state when chlorophyll receives energy from sunlight.

Excessive sunshine is the main cause of leaves turning a darker green color. Lack of sunlight causes a plant's leaves to create more chlorophyll, which is what gives the plant its green hue.

The color of the leaf is darker green than typical because of the increase in chlorophyll concentration per unit area.

<h3>What is photon theory?</h3>

The photon theory of light states that photons have simultaneous particle and wave behavior. pass through empty space at a constant speed, or "the speed of light". possess rest energy and zero mass.

Formula los siguientes compuesto: Dietil eter, Etanol, Propanotriol, Acido Propanodioico, Pentanal, Pentano-2,4-diona, Metanoato

9966 [12]

Answer:

Explanation:

En este caso para formular los compuestos, debes identificar el grupo funcional principal de la molecula. Una vez que eso está hecho, puedes intentar formularlo.

Empezaremos primero identificando el grupo funcional principal de la molécula, para luego formularlo correctamente.

Dietil eter: la terminación eter al final significa que pertenece al grupo de los éteres, el cual tiene como formula general R - O - R.

Etanol: debido a que termina en ol, este grupo pertenece a los alcoholes. Para formularlo solo se dibuja la molecula del etano, junto a un enlace con el grupo OH, como su formula general R - OH.

Propanotriol: igualmente termina en ol, por lo tanto es un alcohol, sin embargo, en este caso, tambien tiene la terminación prefija tri, asi que significa que hay 3 grupos OH en la molecula.

Acido propanodioico: esta es sencilla, porque empieza como acido, y solo hay un grupo funcional que empieza así y son los acidos carboxilicos, es decir, el grupo COOH (R - COOH) que es el carboxilo. Tiene el prefijo di, antes del oico, por lo que son dos carboxilos presentes en la molecula.

Pentanal: el sufijo al, significa que pertenece al grupo de los aldehidos, en este caso, posee el grupo carbonilo H - C = O.

Pentano - 2,4 - diona: la terminación ona significa que pertenece al grupo de las cetonas, (R - CO - R), parecido a los aldehidos, con la diferencia de que tiene grupos alquilos en lugar de un hidrogeno.

Metanoato de metilo: la terminación ato de ilo, pertenece a los esteres, (R - COOR) derivado de los acidos carboxilicos.

De aqui en adelante solo mencionaré los grupos funcionales pues ya se explicó el por que, por sus terminaciones:

Ciclohexano - 1.3 - diol: este pertenece a los alcoholes.

Acido heptanoico: acido carboxilico

Ciclobutil metil eter: eteres

Acetato de etilo: ester

2-metilbenzaldehído: aldehído unido a un grupo aromatico como el benceno.

Ciclohexanona: un ciclo (cadena cerrada) unido a un grupo carbonilo.

Butanona: cetona.

How does the design of an experiment relate to the method of difference?

BartSMP [9]

Answer:

The design of experiments (DOE, DOX, or experimental design) is the design of any task that aims to describe and explain the variation of information under conditions that are hypothesized to reflect the variation. The term is generally associated with experiments in which the design introduces conditions that directly affect the variation, but may also refer to the design of quasi-experiments, in which natural conditions that influence the variation are selected for observation.
